+
+## 1. v2 核查总结
+
+### 1.1 核查范围
+
+并行核查了 7 个上游模块的 nextstep-v2.md：
+
+| 模块           | 负责人 | 文档位置                                                                                    | v2 对 api-gateway 的要求                         | 核查结果  |
+| -------------- | ------ | ------------------------------------------------------------------------------------------- | ------------------------------------------------ | --------- |
+| admin-portal   | ai16   | [apps/admin-portal/docs/nextstep-v2.md](../../../apps/admin-portal/docs/nextstep-v2.md)     | `/api/admin/graphql` 路由 + AdminRoleMiddleware  | ✅ 已完成 |
+| teacher-portal | ai13   | [apps/teacher-portal/nextstep-v2.md](../../../apps/teacher-portal/nextstep-v2.md)           | `/api/v1/teacher/*` 反向代理                     | ✅ 已完成 |
+| student-portal | ai14   | [apps/student-portal/docs/nextstep-v2.md](../../../apps/student-portal/docs/nextstep-v2.md) | `/api/v1/student/*` 反向代理 + 路径重写          | ✅ 已完成 |
+| parent-portal  | ai15   | [apps/parent-portal/docs/nextstep-v2.md](../../../apps/parent-portal/docs/nextstep-v2.md)   | Docker 构建修复                                  | ✅ 已完成 |
+| teacher-bff    | ai03   | [services/teacher-bff/docs/nextstep-v2.md](../../teacher-bff/docs/nextstep-v2.md)           | `/api/v1/teacher/*` + `/api/admin/graphql` 代理  | ✅ 已完成 |
+| student-bff    | ai04   | [services/student-bff/docs/nextstep-v2.md](../../student-bff/docs/nextstep-v2.md)           | `/api/v1/student/*` 路径重写剥离 /api/v1/student | ✅ 已完成 |

+
+### 1.2 v2 关键发现
+
+**admin-portal v2 核查发现**：v1 声称已完成的工作（admin 路由、AdminRoleMiddleware、NewProxyRewrite、registerBffProxy）在代码中**实际缺失**（可能被回滚）。v2 重新实现并验证通过。
+
+**parent-bff v2 核查发现**：parent-bff GraphQL 端点路径采用 ARB-022 §24.4 ISSUE-003 方案 A（双 /v1 前缀），即 `/api/v1/parent/v1/graphql` → 剥离 `/api/v1/parent` → `/v1/graphql`。api-gateway 的 `registerBffProxy` 已支持此路径重写。
+
+### 1.3 本地 Docker 验证结果（2026-07-14 v2）
+
+测试环境：本地 Docker（edu/api-gateway:test 容器，DEV_MODE=true，端口 18080→8080）
+
+```
+镜像：edu/api-gateway:test（golang:1.25-alpine builder + alpine:3.20 runner）

+## 2. v2 完成项详情
+
+### 2.1 admin-portal P0 阻塞项（重新实现）
+
+**来源**：[admin-portal nextstep-v2.md](../../../apps/admin-portal/docs/nextstep-v2.md) §2.1
+
+| #   | 工作项                         | 状态 | 实现详情                                                                                                         |
+| --- | ------------------------------ | ---- | ---------------------------------------------------------------------------------------------------------------- |
+| 1   | 新增 `/api/admin/graphql` 路由 | ✅   | [main.go](../main.go) L110-129 新增 `/api/admin` 路由组，POST /api/admin/graphql 代理到 teacher-bff:3003/graphql |
+| 2   | admin 角色强制校验中间件       | ✅   | [admin_role.go](../internal/middleware/admin_role.go) `AdminRoleMiddleware`，校验 x-user-roles 含 admin 角色     |
+| 3   | 路径对齐契约 §2.3              | ✅   | /api/admin/graphql 为唯一入口，路径重写 /api/admin/graphql → /graphql（teacher-bff @Controller("graphql")）      |
+| 4   | AdminRoleMiddleware 单元测试   | ✅   | [admin_role_test.go](../internal/middleware/admin_role_test.go) 8 个测试（含角色列表/空值/大小写）               |
+
+**中间件链**：熔断（teacher-bff-admin）→ JWT 鉴权 → AdminRoleMiddleware → 指标 → 反向代理
+
+### 2.2 BFF 路由路径重写修复（重新实现）
+
+**来源**：[student-bff nextstep-v2.md](../../student-bff/docs/nextstep-v2.md) §3.1、[parent-bff nextstep-v2.md](../../parent-bff/docs/nextstep-v2.md) §3.1
+
+**问题**：teacher-bff / student-bff 的 GraphQL 端点在 `/graphql`（`@Controller("graphql")`），parent-bff 在 `/v1/graphql`（ARB-022 §24.4 ISSUE-003 方案 A）。原代理仅剥离 `/api` 前缀，导致下游收到 `/v1/teacher/graphql` 而非 `/graphql`，返回 404。
+
+**修复**：新增 `registerBffProxy` 函数，对 BFF 路由（teacher/student/parent）剥离 `/api/v1/{bff}` 前缀，仅转发剩余路径到下游。
+
+| 路由                        | 路径重写               | 下游接收路径  | 下游服务         |
+| --------------------------- | ---------------------- | ------------- | ---------------- |
+| `/api/v1/teacher/graphql`   | 剥离 `/api/v1/teacher` | `/graphql`    | teacher-bff:3003 |
+| `/api/v1/student/graphql`   | 剥离 `/api/v1/student` | `/graphql`    | student-bff:3009 |
+| `/api/v1/parent/v1/graphql` | 剥离 `/api/v1/parent`  | `/v1/graphql` | parent-bff:3010  |
+| `/api/admin/graphql`        | 剥离 `/api/admin`      | `/graphql`    | teacher-bff:3003 |
+
+**关键文件**：
+
+- [main.go](../main.go) L180-198 `registerBffProxy` 函数
+- [proxy.go](../internal/proxy/proxy.go) L31-49 `NewProxyRewrite` 函数
+- [proxy_rewrite_test.go](../internal/proxy/proxy_rewrite_test.go) 5 个测试（路径剥离/查询参数/无效URL/请求体/请求头）
+
+### 2.3 Dockerfile 修复
+
+**问题**：
+
+1. go.work 引用了 push-gateway，但 Docker 构建上下文仅含 api-gateway + shared-go，导致 `go mod download` 失败
+2. 容器内无法访问 proxy.golang.org，需使用国内代理
+
+**修复**：
+
+- 生成精简版 go.work（仅 api-gateway + shared-go）
+- 设置 `GOPROXY=https://goproxy.cn,direct` + `GOSUMDB=off`
+- 构建上下文改为仓库根目录（访问 packages/shared-go）

+
+## 1. 概述
+
+api-gateway 是 Edu 系统统一入口（L3 网关层），负责路由转发、JWT RS256 验签、限流、熔断、CORS、可观测性。本文档记录基于上游 4 个前端 portal 模块（teacher-portal / student-portal / parent-portal / admin-portal）的下游依赖分析，梳理 api-gateway 已完成工作与剩余阻塞项。
+
+**本地 Docker 测试结果（2026-07-13）：**
+
+- ✅ 镜像构建成功（`edu/api-gateway:test`，golang:1.25-alpine + 多阶段构建）
+- ✅ 容器启动正常（端口 8080，DevMode）
+- ✅ `/healthz` 返回 200
+- ✅ `/readyz` 返回 503（下游未启动时正确报告不可达）
+- ✅ `/metrics` 返回 200 + Prometheus 格式（7 个业务指标可见）
+- ✅ `/api/admin/graphql` 无 auth → 401（AuthMiddleware 拦截）
+- ✅ `/api/admin/graphql` dev-token → 502（路由存在，admin 角色通过，下游 teacher-bff 不可达）
+- ✅ `/api/v1/teacher/graphql` dev-token → 502（路由存在，BFF 路径重写正确，下游不可达）
+- ✅ go vet + go build + go test 全部通过（13 个新测试）
+
+---
+
+## 2. 已完成工作（基于上游 portal 依赖分析）
+
+### 2.1 admin-portal P0 阻塞项（已解决）
+
+**来源**：[admin-portal nextstep.md](../../../apps/admin-portal/docs/nextstep.md) §2.1
+
+| #   | 工作项                         | 状态 | 实现详情                                                                                         |
+| --- | ------------------------------ | ---- | ------------------------------------------------------------------------------------------------ |
+| 1   | 新增 `/api/admin/graphql` 路由 | ✅   | main.go 新增 `/api/admin` 路由组，POST /api/admin/graphql 代理到 teacher-bff:3003/graphql        |
+| 2   | admin 角色强制校验中间件       | ✅   | 新增 `AdminRoleMiddleware`（internal/middleware/admin_role.go），校验 x-user-roles 含 admin 角色 |
+| 3   | 路径对齐契约 §2.3              | ✅   | /api/admin/graphql 为唯一入口，路径重写 /api/admin/graphql → /graphql（teacher-bff @Controller） |
+
+**关键文件**：
+
+- [main.go](../main.go)（L107-126，admin 路由组注册）
+- [internal/middleware/admin_role.go](../internal/middleware/admin_role.go)（AdminRoleMiddleware 实现）
+- [internal/proxy/proxy.go](../internal/proxy/proxy.go)（NewProxyRewrite 路径重写代理）
+
+### 2.2 BFF 路由路径重写修复（已解决）
+
+**来源**：[student-portal nextstep.md](../../../apps/student-portal/docs/nextstep.md) §2、[teacher-portal nextstep.md](../../../apps/teacher-portal/nextstep.md) §4.3
+
+**问题**：teacher-bff / student-bff / parent-bff 的 GraphQL 端点在 `/graphql`（@Controller("graphql")），但原代理仅剥离 `/api` 前缀，导致下游收到 `/v1/teacher/graphql` 而非 `/graphql`，返回 404。
+
+**修复**：新增 `registerBffProxy` 函数，对 BFF 路由（teacher/student/parent）剥离 `/api/v1/{bff}` 前缀，仅转发剩余路径到下游。
+
+| 路由                    | 修复前（错误）                              | 修复后（正确）               |
+| ----------------------- | ------------------------------------------- | ---------------------------- |
+| /api/v1/teacher/graphql | → teacher-bff:3003/v1/teacher/graphql (404) | → teacher-bff:3003/graphql ✓ |
+| /api/v1/student/graphql | → student-bff:3009/v1/student/graphql (404) | → student-bff:3009/graphql ✓ |
+| /api/v1/parent/graphql  | → parent-bff:3010/v1/parent/graphql (404)   | → parent-bff:3010/graphql ✓  |
+
+**契约依据**：student-portal_contract.md §2.3「/api/v1/student/* → student-bff:3009/*」
+
+### 2.3 Docker 构建修复（已解决）
+
+**问题**：原 Dockerfile 使用 golang:1.22-alpine 且构建上下文为 service 目录，无法解析 shared-go 依赖（go.work 模式）。
+
+**修复**：
+
+- 升级基础镜像为 golang:1.25-alpine（匹配 go.work 的 go 1.25.0）
+- 构建上下文改为仓库根目录（访问 packages/shared-go）
+- 生成精简版 go.work（仅含 api-gateway + shared-go，排除 push-gateway）
+- 设置 GOPROXY=https://goproxy.cn,direct（国内网络环境）

+
+#### 3.7.4 api-gateway（ai01）依赖
+
+| 依赖项                               | 状态      |
+| ------------------------------------ | --------- |
+| HTTP `GET /healthz` :3004            | ✅ 已实现 |
+| HTTP REST `/api/v1/exams/*` :3004    | ✅ 已实现 |
+| HTTP REST `/api/v1/homework/*` :3004 | ✅ 已实现 |
+| HTTP REST `/api/v1/grades/*` :3004   | ✅ 已实现 |
+| HTTP REST `/api/v1/classes/*` :3004  | ✅ 已实现 |
+
+#### 3.7.5 4 个 portal（ai13/14/15/16）间接依赖
+
+portal 不直接调用 core-edu，通过各自 BFF 转发。需求已在 §3.7.1-3.7.3 中体现。
+
+#### 3.7.6 潜在缺口说明（parent-bff/parent-portal 提及）
+
+> parent-bff §4.6 降级查询清单和 parent-portal §4.2 提到 `ExamResultService` 和 `ExportService`，这两个 Service 在 core-edu 9 Service / 40 RPC 清单中不存在。
+
+| 下游提及的能力                    | core-edu 现状                                                                     | 归属判断                                                                 |
+| --------------------------------- | --------------------------------------------------------------------------------- | ------------------------------------------------------------------------ |
+| 考试结果详情（ExamResultService） | GradeService.GetReportCard 可承接成绩报告卡；ExamService.GetExam 返回考试基础信息 | 需 parent-bff 联调时确认是否需要独立 RPC，或由现有 RPC 组合              |
+| 成绩导出（ExportService）         | 无对应 RPC（导出属 BFF/Portal 层格式化能力）                                      | 建议由 parent-bff 调用 GradeService.ListGradesByStudent + 本地格式化实现 |
+
+**结论**：这两项不阻塞下游联调，core-edu 不新增 RPC，待 parent-bff 联调时协商归属。

+## 4. 已完成的工作（本轮）
+
+### 4.1 Announcements 公告功能（新增）
+
+**原因**：下游 teacher-bff / student-bff / admin-portal 均需要公告 CRUD + 已读标记，msg 原仅有通知能力。
+
+**实现**：
+
+- `src/announcements/announcements.schema.ts` — Drizzle schema（msg_announcements + msg_announcement_reads 表）
+- `src/announcements/announcements.repository.ts` — 数据访问层
+- `src/announcements/announcements.service.ts` — 业务逻辑
+- `src/announcements/announcements.controller.ts` — REST API（8 端点）
+- `src/announcements/announcements.module.ts` — 模块定义
+- `src/middleware/permission.guard.ts` — 新增 `MSG_ANNOUNCEMENT_MANAGE` / `MSG_ANNOUNCEMENT_READ` 权限
+- `infra/init-sql/02-all-services-schema.sql` — 新增 msg_announcements / msg_announcement_reads 表
+
+**REST 端点**：
+
+| 路径                       | 方法   | 权限                    | 说明                              |
+| -------------------------- | ------ | ----------------------- | --------------------------------- |
+| /announcements             | POST   | MSG_ANNOUNCEMENT_MANAGE | 创建公告（draft）                 |
+| /announcements             | GET    | MSG_ANNOUNCEMENT_READ   | 列表（支持 status/audience 筛选） |
+| /announcements/:id         | GET    | MSG_ANNOUNCEMENT_READ   | 详情                              |
+| /announcements/:id         | PUT    | MSG_ANNOUNCEMENT_MANAGE | 更新                              |
+| /announcements/:id         | DELETE | MSG_ANNOUNCEMENT_MANAGE | 删除                              |
+| /announcements/:id/publish | PUT    | MSG_ANNOUNCEMENT_MANAGE | 发布                              |
+| /announcements/:id/archive | PUT    | MSG_ANNOUNCEMENT_MANAGE | 归档                              |

+| /announcements/:id/read    | POST   | MSG_ANNOUNCEMENT_READ   | 标记已读                          |
+
+### 4.2 ARB-008 / ARB-013 落地（前序已完成）
+
+- proto RPC 17→13（裁剪 4 RPC 降级 REST only）
+- topic 命名 `edu.notify.notification.*`
+- /readyz 6 依赖检查（Kafka producer/consumer 拆分）
+- sendBatch 批量 INSERT 优化
+
+### 4.3 sendBatch 批量 INSERT 优化 + eventId 幂等过滤（本轮）
+
+**原因**：下游 BFF 批量发送通知时性能不佳，原实现循环调用 `send`（每条 insert + dispatch + outbox）。此外 sendBatch 缺少 eventId 幂等检查，重复发送会重复插入。
+
+**改动**：
+
+- `src/notifications/notifications.service.ts` — sendBatch 改为先批量 `insertNotifications(rows)`，失败时全部标记 failed；成功后逐条 ES 索引 + dispatch + outbox
+- `src/notifications/notifications.repository.ts` — 新增 `findExistingEventIds(eventIds)` 批量查询已存在的 eventId
+- `src/notifications/notifications.service.ts` — sendBatch 批量 INSERT 前先调用 `findExistingEventIds` 过滤已存在的 eventId（幂等跳过）
+- 批量 INSERT 失败 → 所有 items 进 failed 列表
+- 部分分发失败 → 仅失败项进 failed 列表，成功项进 ids
+- eventId 已存在 → 跳过该项（不插入、不分发、不写 outbox），返回空 ids
+- 无 eventId 的 item → 正常插入（不做幂等检查，与单条 send 行为一致）
+
+**幂等行为**：
+
+- 全部 eventId 已存在 → 返回 `{ ids: [], failed: [] }`
+- 部分 eventId 已存在 → 仅插入未存在的，已存在的跳过
+- 无 eventId → 正常插入（允许重复）
+
+**单元测试**（新增 2 个）：
+
+- `eventId 已存在时应跳过（幂等过滤）` — 2 条 items（1 已存在 + 1 新），仅插入 1 条
+- `所有 eventId 都已存在时应返回空 ids（全跳过）` — 2 条都已存在，不调用 insertNotifications
+
+### 4.4 Docker 本地测试验证（本轮，无 mock 数据）

+## 7. msg 模块工作完成总结
+
+### 7.1 已完成的全部工作
+
+1. **P5 通知中台核心**：13 gRPC RPC + 10 REST endpoints（notifications）+ 2 REST endpoints（preferences）+ 6 REST endpoints（templates）
+2. **ARB-008 裁决落地**：RPC 17→13，4 RPC 降级 REST only
+3. **ARB-013 topic 统一**：`edu.notify.notification.sent/read/recalled/failed`
+4. **Outbox + 三层幂等**：msg_outbox_events + Redis SETNX + DB + event_id UNIQUE
+5. **ChannelDispatcher**：5 通道 Promise.allSettled
+6. **/readyz 6 依赖检查**：DB/ES/Redis/KafkaProducer/KafkaConsumer/PushGateway
+7. **Announcements 公告模块**：9 REST endpoints（schema+repo+service+controller+module）
+8. **sendBatch 批量优化**：循环单条插入 → 批量 insertNotifications
+9. **权限扩展**：MSG_ANNOUNCEMENT_MANAGE/READ + parent 角色
+10. **Docker 本地测试**：18 项 API 全部验证通过（真实 DB，无 mock）
+11. **单元测试**：99 tests / 5 spec files 全部通过
+12. **SQL Schema**：msg_announcements + msg_announcement_reads 表
+13. **Dockerfile**：workspace 模式多阶段构建
+14. **文档**：nextstep.md 完整上下游依赖 + Docker 测试结果
+
+### 7.2 msg 模块对外提供的能力清单
+
+**gRPC（端口 50056，13 RPC）**：
+
+- NotificationService: SendNotification, ListNotifications, MarkAsRead, SearchNotifications, RecallNotification
+- NotificationPreferenceService: GetPreferences, UpdatePreferences
+- NotificationTemplateService: CreateTemplate, GetTemplate, ListTemplates, UpdateTemplate, DeleteTemplate, RenderTemplate
+
+**REST（端口 3007）**：
+
+- /notifications/*（10 endpoints）
+- /preferences/user/:userId（2 endpoints）
+- /templates/*（6 endpoints）
+- /announcements/*（9 endpoints）
+- /healthz, /readyz, /metrics
+
+**Kafka 消费（12 类事件）**：
+
+- iam: 6 类 identity 事件
+- core-edu: 5 类 teaching 事件
+- data-ana: 1 类 insight 事件
+
+**Kafka 发布（4 类事件）**：
+
+- `edu.notify.notification.sent/read/recalled/failed`
+- DLQ: `edu.notify.dlq`
